The title character of Ray Bradbury’s book The Illustrated Man is covered with moving, shifting tattoos. If you look at them, they will tell you a story.New LED tattoos from the University of Pennsylvania could make the Illustrated Man real (minus the creepy stories, of course). Researchers there are developing silicon-and-silk implantable devices which sit under the skin like a tattoo. Already implanted into mice, these tattoos could carry LEDs, turning your skin into a screen. [The most cool mice in the world] The silk substrate onto which the chips are mounted eventually dissolves away inside the body, leaving just the electronics behind. The silicon chips are around the length of a small grain of rice — about 1 millimeter, and just 250 nanometers thick. The sheet of silk will keep them in place, molding to the shape of the skin when saline solution is added.These displays could be hooked up to any kind of electronic device, also inside the body. Medical uses are being explored, from blood-sugar sensors that show their readouts on the skin itself to neurodevices that tie into the body’s nervous system — hooking chips to particular nerves to control a prosthetic hand, for example.Chips are already used inside bodies, most notably the tiny RFID tags injected into pets. But the flexible nature of these “tattooed” circuits means they can move elastically with the body, sitting in places that a rigid circuit board couldn’t.The first displays are sure to be primitive, but likely very useful for the patients that receive them. You won’t be getting the full-color, hi-res images that come with ink, but functional displays. This doesn’t mean that the commercial and artistic possibilities are being ignored. Philips, the electronics giant, is exploring some rather sexual uses.It’s certainly rather creepy, but we’re sure that the inevitable next stage of playing adult movie clips on your partner’s back will be appealing to some. We, of course, are considering the geekier side of this tech. GPS, with a map readout on the back of the wrist would certainly be useful, as would chips that cover your eyeballs and can darken down when the sun is shining too bright.And a full-body display will eventually be used for advertising. Combine this with bioluminescent ink, for example, and you could turn yourself into a small, walking version of Times Square. At least, unlike a real tattoo, you can switch this one off.In fact, if you start to imagine the possible uses, they seems almost endless. Just like the stories that play across the body of the Illustrated Man.

“Like in other countries there is a mania for tattoos among criminals, but in Russia they give much more sense for those signs on their bodies. Each even smallest detail can be interpreted as a biography verse from the life of tattoo owner, both police and criminals can just look at the body of the tattooed person and tell all his deeds. They say these days there more freedom is allowed in decorating their bodies such way, but during the Soviet regime a person could earn big disgrace from his friends if he made a tattoo not according the rules.”

When I was looking for a second tattoo idea, I discovered this canadian tattoo artist. Probably I will draw it by myself, but I like this guy. I like the character of the random lines and childish drawings, but they seem a little emo.
